Improvement in steam-cultivator



is revolvcd, it gives oil' one rope and takes on the other, thus 4letting forward one wheel, whilst bringing back end to turnit by; so, when the other. The machine is in this manner directed.

Another means of steering may be to'secnre a segment of a gear-wheel to the mile, and operate to turn round the axle and steering-wheels, by having a pinion-gear engaging with the segment-gear, and which may ber-evolved by a hand-wheel on the upper' end of a vertical shaft, to the lower end of which the pinion would be secured, the vertical shalt itself heilig secured to the main frame.

However', the particular means to be adopted for steering need scarcely be specified, for there are many v wheels and theplow-cylinder, the eil'ect'being tol pn einen means equally applici'rhle, and I shall Anot claim the steering-rig as part of my invention. Y

I may, it I wish, provide a means of throwing in and outZ of gear, any one. sepamte, or all the gear- I wheels on my machine; as, for instance, I maygwislr to run the driving-wheels and not the plow-cylinder; or, I may wish to runthe engine aloue,-when punrp ing up the boiler; or .l may wish to drag the machine from place to place by horses, &c.

l The means I shall adopt for this purpose will be the common and well-known jaw-clntch,.whieh, engaging with the hub of the gear to whichy it is applied, is thrown in and out by a hand-lever, the clutch sliding on a feather on the shaft, and the geant/heel being loose, The device is well known to those pmetised in the art.

The machine will be covered in by a suitable platl form of wood, which is not shown on drawing, because it would hide the parts; and a watentank may he provided, if found convenient.

The opcrationofmy invention is as follows:

Steam is generated in the holler, und the engines supplied therefrom, which, wheny set in motion, revolve the 4system of gearing.V which revolves the drivingpel the machine forwarsnd, at the same time, to plow up the soil in a most thorough manner.

The knives set in the frame will actas before suggested, to cut up and divide the clodn, and the seeder will scatter the seed, and'- when the harrowls used, it

.to plow the ground.

will operate to cover' up the seed and level ofi' the ground. f i i It will be observed, that since the plowcylinder will revolve at double the speed of the driving-wheels, it will necessalily act to propel the machine, aswell ns I dscla'in any novelty in' the har-row or seeder, or

in the aplicationthereofinthiscase;but

'What claim as my invent-lon, a'nd desire to secure by Letters Patent, is-

1. The revolving plow-cylinder, hnvlng the plows Vsecured thereon, and adjustable in the pedestnls, and

the system of gearing trans hitting motion between the engines, the plow-cylinder', and the driving-wheels, in combination therewith, substantially as herein described, and for the purposes as set forth.v

2. "lhe adjustable frame of knives, (set in rear of plow-cylinder,) which slides np and down on the guidehars, constructed substantially as herrin described, und for the purposes as set forth.' ANDREW JACKSON STEVENS.
